Question about 1989 GMC Sierra
I need to replace a transmission in an 89 GMC Sierra. I am looking for one at a junk yard. What other years/models will work in this truck? Thanks.
If it has a 4.3 liter motor a 86 to a 97 if it has a 350 motor a 81 to a 96 will work hope this helps

1989 has 3 transmissions that fit, the 3 speed TH350, and TH400 (D, 2 &1) and if equiped with over drive or 4 spped the TH700 R4 (OD, 3, 2 & 1) Shift indicator will show which speed transmission you have but the fluid pan configuration idenfies the exact type of 3 or 4 speed.
